And some of the advice that SAGE has considered since the beginning of February has also been opened up for scrutiny, including evidence, as we revealed last week, showing that there were warnings about the potentially catastrophic impact of the virus several weeks before the sudden lockdown.

There is, though, a lot more of the evidence that is still being withheld, most importantly the actual advice SAGE has given to ministers.

It's right that the government and its advisers are held to account over their handling of the coronavirus crisis.

Other countries saw the warning signs far earlier than the UK. We were the last major European country to lockdown, we took too long to ramp up testing and the provision of PPE for health and care workers has been hopelessly inadequate.

The independent SAGE group has added its own criticisms about the premature abandonment of contact tracing in early March, the reliability of the testing figures announced in the government's daily news briefing and the junking of the clear "stay at home" message as the lockdown is lifted.

But some of its recommendations are consistent with government policy.

They say the virus should be suppressed and not allowed to spread, even in a controlled way. Tick. The government says the R number must be kept below one so the epidemic shrinks.

They want a return to contact tracing. Tick. There's an app being tested and 18,000 virus detectives being recruited.

And they want more real-time, real-world data to get a more reliable picture of what the virus is doing. Tick. The Office of National Statistics has just published the first batch of data from viral swabs on more than 7,000 people.
